From 72719d2f8ae5022fb45d3020d85a644da8884f2a Mon Sep 17 00:00:00 2001 From: Philippe CORNU Date: Thu, 3 Aug 2017 12:36:08 +0200 Subject: video: add STM32 LTDC display controller The STM32 LTDC display controller provides a parallel digital RGB and signals for horizontal, vertical synchronization, Pixel Clock and Data Enable as output to interface directly to a variety of LCD and TFT panels. The LTDC main features are: - 24-bit RGB Parallel Pixel Output, Programmable timings & polarity for HSync, VSync and Data Enable. - 2 layers with Blending, Color Keying, Window position & size, Dithering, Background color, Color Look-Up Table (CLUT). - Supported layer color formats: ARGB8888, RGB888, RGB565, ARGB1555, ARGB4444, L8 CLUT, AL44 & AL88 This LTDC driver: - supports: RGB parallel output with timings & polarity, 1 layer in RGB565. - supports but with hard-coded configurations: blending, window position & size (crop), background color. - does not support yet: rgb888, argb8888, 8-bit clut, dithering. This LTDC driver is compatible with all stm32 platforms with the LTDC IP and has been tested on stm32 f746-disco board.
